EMA 200 (3+7 crossover)

The EMA 200 (3+7 crossover) indicator provides a versatile trend-following system that utilizes three customizable moving averages to identify momentum shifts and long-term market reversals.

Usage

The indicator is used to identify trend direction and potential entry or exit points through the interaction of three moving averages: Fast, Slow, and Turtle.

• Momentum Signals: When the Fast MA crosses the Slow MA, it indicates a short-term shift in momentum. Traders often use these crossovers as early signals for potential trend changes.
• Trend Confirmation: The Turtle MA (defaulted to 200) serves as the primary trend filter. When price or shorter-term MAs are above the Turtle MA, the market is generally considered to be in an uptrend.
• Golden and Death Crosses: By monitoring the crossover between the Slow MA and the Turtle MA, the script identifies major trend shifts. A "Golden Cross" occurs when the Slow MA crosses above the Turtle MA, while a "Death Cross" occurs when it crosses below.

Details

The script is built to be modular, allowing users to choose between several moving average types, including Exponential (EMA), Simple (SMA), Hull (HMA), Weighted (WMA), and Volume-Weighted (VWMA). This flexibility allows the tool to be adapted for different asset classes and trading styles.

The visual output distinguishes the three averages clearly:

• MA Fast & MA Slow: Displayed as solid lines to track immediate price action.
• MA Turtle: Displayed as a series of circles. The color of the Turtle MA dynamically shifts based on the relationship between the Fast and Slow MAs, providing a visual cue for current momentum relative to the long-term trend.
• Crossover Markers: When enabled, the script plots specific symbols to highlight major trend transitions between the Slow and Turtle periods.

Settings

• MA type: Selection for the calculation method (EMA, SMA, Hull, WMA, or VWMA).
• Price: The source input for the moving average calculations, typically set to "close".
• MA Fast: The period for the shortest moving average (default 13).
• MA Slow: The period for the medium-term moving average (default 48).
• MA Turtle: The period for the long-term trend moving average (default 200).
• View MA Slow/Turtle crossover: A toggle to enable or disable visual markers for major trend crossovers on the chart.

FAQ

Which moving average types are supported? The indicator supports Exponential (EMA), Simple (SMA), Hull (HMA), Weighted (WMA), and Volume-Weighted (VWMA) calculations.

What is the "Turtle" moving average? The Turtle MA is a long-term trend baseline, traditionally set to a 200-period length, used to determine the overall market bias.
